Fix setAnimatedNodeValue in Native Animated on iOS

Summary:
`setAnimatedNodeValue` currently does not update views if there is no animation currently running. This simply updates the view immediately instead of relying on the animation loop. Extracted it out in a function to be able to use it for native `Animated.event` too.

**Test plan**
Tested this in an app using native driven animations with `NavigationCardStackPanResponder` that makes use of `setValue` to update `Animated.Values` during the back gesture.
